WIND sre v.

Application filed February 8, 1922. Serial No. 535,100.

To (ZZZ whom it may concern:

Be it known that I, HUGH CoRRnLL, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful lVind Sign, of which the following is a specification.

This invention relates to improvements in wind signs and has for its objects to provide a device of this character including a revoluble frame having a plurality of revoluble vanes mounted thereon; to construct the vanes so that they will all remain in substantially the same position as the frame revolves; and to provide a brake upon the revoluble frame automatically controlled by the centrifugal pull of the vanes to prevent too rapid rotation of the revoluble frame.

The above and other objects may be attained by providing a construction such as illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a wind sign en'ibodying the invention;

Fig. 2, a side elevation partly in section of a portion of the revoluble frame, showing one of the vanes;

Fig. 3, an edge elevation of one of the vanes;

Fig. 4, an enlarged, vertical, sectional view through the journal portions of one vane;

Fig. 5, a section on the line 5-5, Fig. 4;

Fig. 6, a vertical section through the journal portion of the revoluble frame; and

Fig. 7, a sect-ion on the line 7-7, Fig. 6.

Similar numerals refer to similar parts throughout the drawings.

The device is preferably supported above the ground as by the skeleton frame 1, provided in its upper portion with a pair of spaced plates 2 and 3, having the aligned openings 4 and 5 respectively, and connected to opposite ends of the tube 6.

The central shaft 7, upon which the revoluble frame indicated generally at 8 is mounted, is journaled through the plates 2 and 3, being provided with ball bearings 9 and 10 located in the oppositely disposed cups 11 and 12- respectively of said plates.

A plurality of upper and lower horizontal arms 13 and 14 respectively, are fixed at their inner ends to the upper squared portion 15 of the shaft 7 as by the brackets 16. The revoluble frame is strengthened by connecting these arms by the vertical brace rods 17 and the horizontal brace rods 18. i

The outer ends of the arms 13 carry the bearings 19, in each of which is provided a ball bearing 20, a concaved cap 21 resting upon said ball bearing and supporting the upper spindle 22 of the vane. A washer 23 and nut 24 are carried by the upper end of this spindle for engagement with the cap, the cap being provided with the central opening 25 of greater diameter than the spindle.

Each vane indicated generally at26 comprises the upper and lower V-shaped structural frames 27 connected at intervals by the vertical braces 28. Metal platesor sheets 29 Y are connected to the frames of the vanes extending from the apex of each vane to a point beyond the center thereof, a wire mesh 30 covering the remaining portion of the frame of each vane.

Plates 31 are connected to the upper and lower edges of the vanes at the vertical center thereof. The upper spindle 22 is provided with the lower threaded extremity which is received through the upper plate 31, nuts 32 being provided upon opposite sides of the plate by means of which the vane may be adjusted vertically;

A bearing 33 is carried at the extremity of each lower arm 14 of the frame and contains a bushing 34 provided with the oblong socket 35, which receives the lower spindle 36 of the vane. The lower spindle is adjustably connected to the lower plate 31 of the vane by the nuts 37. As illustrated, each vane is journaled near one end of the imperforate portion.

A brake drum 38 is fixed upon the plate 2 and contains a pair of half round Wooden brake shoes 39, each of which is connected to one end of a lever 40 pivoted intermediate its ends as at 41 upon the revoluble frame, the link 42 connecting the other end of the lever with the sleeve 43, rotatably mounted upon the lower spindle 36.

hen the wind strikes the sign, the V- shaped pocket in each vane will receive the wind, causing the apex of each vane to be pointed away from the wind, the imperforate end of each vane acting as a rudder to hold the vane in the same position as the revoluble frame is rotated. The revoluble frame is arranged to be rotated slowly by the action of the wind upon the vanes, displaying the advertising matter upon each vane as the frame rotates.

In the event the wind causes too rapid rotation of the revoluble frame, the lower spindles 36 of the vanes will be thrown outward by centrifugal force and through the links 42, the brake shoes will be moved into engagement with the brake drum, reducing the speed at which the frame is revolved.

It will be understood that the vanes may be pivoted substantially in the middle of their length, as shown in the drawings, for the reasonthat one end of the vane is made heavier than the othercnd, which may be, and preferably is done by forming aportion at least ofone end of the vane of perforate or wire mesh material, which not only makes this end lighter than the other end, but lessens its relative resistance to the wind.

The vanes do not rotate at. a high rate of speed, but maintain substantially the same position throughout each complete cycle of-the frame, each vane making substantially one-half of a complete rotation and moving back to its original position in each complete revolution of the frame. The Wind striking the vanes causes the entire frame to revolve upon its axis as the frame is journaled upon roller bearings and is easily moved by any slight force applied to the vanes.

It ,is .believedthat the vanes toward the wind will, to some extent,.shield the vanes farthest from the wind from the full force of the wind, thus starting the rotation of the device in one direction. As the frame is mounted upon roller bearings, itwill be obvious that as soon as the rotation is started in one direction, it will be continued during the time the wind is blowing from this direction.

I claim 1. A wind sign including a i'evoluble frame, rotatable vanes journaled in said frame, one end portion only of each vane being perforate, so as to point the imperforate end with the wind as the frame revolves.

2. A wind sign including a revoluble frame, V-shaped vanes journaled in said frame, the wide end portion of each vane being perforate so as to point the imperfor ate end with the wind as the frame revolves.

3. A wind sign including a revoluble frame, vanes revoluble in the frame, a brake upon the frame and means controlled by the centrifugal pull of the vanes for applying the brake.

l. A wind sign including a revoluble frame, vanes journaled in the frame, a brake upon the frame and means cont-rolled by the centrifugal pull of the vanes for apply ing the brake.

5. A wind sign including a revoluble frame, vanes journaled in the frame, said journals permitting outward centrifugal movement of the vanes, a. brake upon the revoluble frame and a connection between the brake and the vanes.

6. A wind sign including a revoluble frame, vanes journaled in the frame, said journals permitting outward centrifugal movement-of the vanes, a brake drum upon the revoluble frame, friction means for engaging the brake drum and links connecting the vanes with the friction means.

1. A wind sign including a revolnble frame, vanes journaled in said frame, one end portion only of each vane being pen forate so that the other end will point with the wind.
